The “Sustainable Development” concept emerged during the 1980s in the literature concerned with the problems of the environment and its relationship to development. The report of the United Nations World Commission on Environment and Development (WCED), which was published in 1987 under the title “Our Common Future”, was the first to define sustainable development as being the "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." This means suitable and fair distribution of resources, rights and of wealth among individuals over time and mutual equality between different generations and between members of the same generation.
